Police investigating the suspected murder of a man who went missing in 1992 have released images of a letter they received which claimed to know who was responsible.
Cleveland Police said they received the letter about Steven Clark in 1999, seven years after he disappeared near his home in Marske.
Det Ch Insp Shaun Page said: "The letter was sent to Guisborough Police Station and is very precise in nature. The letter writer intimated that Steven was dead and that they claim to know the person responsible. It was 21 years ago, so the letter writer could have died since then, but if anyone recognises the handwriting, we would urge them to get in touch."
Mr Clark's parents were arrested in September on suspicion of murder but they "absolutely" denied any wrong doing.
Mr Page added: “Steven (pictured above) left his personal belongings at home when he disappeared. His wallet, glasses, and watch. He was a sociable character, and was liked by the friends who knew him. He had lived in South Africa until he was around the age of 20, having moved there when he was younger. His life in Marske was different from the more restricted way of life overseas.”
Anyone with information is asked to call Cleveland Police on 101.
